A small-angle x-ray scattering station at beijing synchrotron radiation facility
TLDR
In this paper, the authors present the development and current state of a small-angle X-ray scattering station at beamline 1W2A of the Beijing Synchrotron Radiation Facility, China.Abstract:
This article presents the development and current state of a small-angle X-ray scattering station at beamline 1W2A of the Beijing Synchrotron Radiation Facility, China. The source of the beamline is introduced from a 14-pole wiggler. A triangular bending Si(111) crystal is used to horizontally focus the beam and provide a monochromatic X-ray beam (8.052 keV). A bending cylindrical mirror coated with rhodium downstream from the monochromator is used to vertically focus the beam. The X-ray beam is focused on the detector which is fixed at 30 m from the source. The focused beam size (full width at half maximum) is 1.4 × 0.2 mm2 (horizontal × vertical) with a flux of 5.5 × 1011 phs/s at 2.5 GeV and 250 mA. Besides the routine mode of small-angle X-ray scattering, the combination of small- and wide-angle X-ray scattering, grazing incidence small-angle X-ray scattering, and time-resolved small-angle X-ray scattering in sub-second level are also available for the users. Dependent on the measurement requirements,...read more

Small-Angle X-Ray Scattering
W. Ehrenberg,A. Franks +1 more
TL;DR: The neighbourhood of the direct beam is, for a variety of reasons, easily obscured by scattered radiation and insufficient collimation, so that special measures such as very long film-specimen distances or focusing crystal monochromators have been used for obtaining satisfactory photographs.
